Mehmet Oz is President Donald Trump’s pick to lead the Centers for Medicare and Medicaid Services, a massive agency that oversees health coverage for more than 100 million Americans, including older adults, those with low incomes and children. 

Oz is a cardiothoracic surgeon and former professor at Columbia University who became a household name when he started appearing on “The Oprah Winfrey Show” in 2004 and then hosted his own show, “The Dr. Oz Show,” from 2009 to 2022. 

On Friday, Oz will face federal lawmakers in a Senate hearing as he seeks confirmation to run CMS, an agency that has a more than trillion-dollar budget and could face spending cuts in the budget year ahead. 

Today on “Post Reports,” health accountability reporter Lauren Weber explains why he may face questions about his past, his investments and possible conflicts of interest.

Today’s show was produced by Elana Gordon. It was edited by Peter Bresnan with help from Maggie Penman and Lynh Bui. It was mixed by Sam Bair.
